FALL RIVER — Since December 2011, a small but intrepid group of charter review advocates have been working to get the 7,381 needed signatures to put a question on the ballot to establish an elected Charter Commission. The group now has nonprofit status, with the Fall River Charter Review Group working to raise money for the effort.

With more than 4,000 signatures to date, the group is more than halfway to its goal.

One of the original members of the group of charter review advocates, board member Susan Mathias said she’s invested in the city and it’s the right thing to do. Mathias said she’s “committed to see this to the end.”

“We are really ramping up our efforts. It’s full steam ahead and there is no looking back,” Mathias said.

City Councilor Michael Miozza, who spearheaded the group before being sworn in as a freshman councilor, said the group has been fundraising to hire a professional signature-gathering company and use some of the funds to start a public education campaign to spread the word of how important it is for the city to review its charter.

The city charter has not been reviewed in decades, despite Massachusetts law requiring the document be reviewed every 10 years.

The charter was adopted when the city was incorporated in 1854.

“We are probably the only community in the commonwealth that has never reviewed its charter,” Miozza said. “There is no mechanism in place for it.”

Miozza said the group plans to bring the 4,000 signatures to the city’s Board of Elections Chairwoman Elizabeth Camara for certification next week.

Most of the seed money to start the fundraising campaign has come from local and state elected officials. Miozza said Mayor Will Flanagan donated $50 to the cause.

On Monday, some of the group’s funds paid for a mass mailing to local businesses to garner support and seek donations.

The group is pursuing a home rule charter method, which requires a ballot vote to establish a charter commission that would be elected by the voters. A second binding election referendum would be held for voters to accept the terms of the charter revision.

Originally the advocates were aiming to put the creation of a commission on the November 2013 ballot, but getting the needed signatures proved a more daunting task than expected, Miozza said.
